Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and more specifically, to a portable welding hopper for vertical welding in confined spaces. Background Technology

[0002] Construction and decoration work involves numerous welding operations. The welding process generates high-temperature electric arcs and weld spatter, which can easily ignite surrounding flammable materials, leading to a fire. Furthermore, the high temperatures during welding can spread not only through weld spatter but also through heat conduction, affecting surrounding combustibles. Therefore, fire-resistant devices are necessary.

[0003] Ordinary fire-welding devices are difficult to adapt to relatively small spaces, especially when welding outdoor round and square steel columns. Ordinary fire-welding devices are inconvenient to use and carry. Summary of the Invention

[0004] In view of this, the present invention proposes a portable fire-receiving bucket for vertical welding in confined spaces, comprising an arc-shaped keel frame and a fireproof board surface laid on it; the two vertical sides of the arc-shaped keel frame can be close to each other and connected together to form a conical fire-receiving bucket, the small arc edges of the arc-shaped keel frame are connected to form a small circle, located at the cone top of the conical fire-receiving bucket, and can cover a part of the steel column or steel pipe to be welded, so that the part to be welded is placed in the conical space of the conical fire-receiving bucket, and the large arc edges of the arc-shaped keel frame are connected to form a large circle, located at the cone bottom of the conical fire-receiving bucket.

[0005] Preferably, the fireproof panel is made of glass fiber fireproof material.

[0006] Preferably, the two vertical sides of the arc-shaped keel frame are respectively provided with adhesive structures, which can stick the two vertical sides together. After use, the two vertical sides can be separated by separating the adhesive structures, so that the arc-shaped keel frame can be restored from the shape of a conical fire bucket to an arc-shaped structure.

[0007] Preferably, the adhesive structure is a Velcro strap, and the two tabs of the Velcro strap are respectively connected to the two vertical sides of the arc-shaped keel frame.

[0008] Preferably, the cone-shaped fire-receiving bucket formed by the arc-shaped keel frame has a cone-shaped coverage height of 300-500mm.

[0009] Preferably, the fireproof board surface made of the glass fiber fireproof material is connected to the arc-shaped keel frame by concealed stitching.

[0010] Preferably, the steel column is a circular steel column or a square steel column.

[0011] Preferably, the steel pipe is a round steel pipe or a square steel pipe.

[0012] This utility model provides a portable welding bucket for vertical welding in confined spaces, which has the following advantages: it can effectively fit round and square steel pipes or steel columns, eliminating the problem of carrying traditional welding buckets; it can better expand the welding area and enhance the efficiency of the welding bucket; the welding bucket is easy to operate, easy to install, and low in cost.

[0019] See Figure 1-3As shown, this is a portable welding hopper for vertical welding in confined spaces provided by an embodiment of the present invention. It includes an arc-shaped frame 1 and a fireproof board surface 2 laid on it. The two vertical sides of the arc-shaped frame 1 can be close together and connected to form a conical welding hopper 5. The smaller arc edges of the arc-shaped frame 1 connect to form a small circle, located at the apex of the conical welding hopper 5, and can enclose a portion of the steel column 4 (or steel pipe 4) to be welded, placing the part to be welded within the conical space of the conical welding hopper 5. The larger arc edges of the arc-shaped frame 1 connect to form a large circle, located at the bottom of the conical welding hopper 5. In specific use, the apex of the conical welding hopper 5 is set downwards. The steel column is a square or round steel column, and the steel pipe is a square or round steel pipe.
